Abstract
A dual band internal antenna for a mobile wireless communication device, having a generally planar radiating element (100) with a high and low band portions, and ground and feed contacts (130, 140) extending from the radiating element. In one embodiment, the width of the ground contact is approximately twice the width of the feed contact. In another embodiment one or more radiating portions (150, 160) extend from the radiating element. In another embodiment, the low band portion has an arm (124) that extends about a tapered lobe (114) of the high band portion.
Claims29
A dual band internal antenna for a mobile wireless communication device, comprising:
- a generally planar radiating element having a high band portion and a low band portion,
- a ground contact extending from the generally planar radiating element;
- a feed contact extending from the generally planar radiating element,
- the ground contact having a width approximately twice a width of the feed contact.
A dual band internal antenna for a mobile wireless communication device, comprising:
- a generally planar radiating element having a high band portion and a low band portion interconnected by a portion of the generally planar radiating element,
- a first radiating portion extending generally perpendicularly from the portion of the generally planar radiating element interconnecting the high band portion and the low band portion;
- a ground contact and a feed contact both extending from the generally planar radiating element on the same side thereof as the first radiating portion.
A dual-band mobile wireless communication device, comprising:
- a non-conductive endo-housing;
- a radio transceiver coupled to a controller;
- user inputs and user outputs coupled to the controller;
- a dual band internal antenna disposed in the housing and coupled to the transceiver, the dual band internal antenna having a ground plane and a generally planar radiating element,
- the generally planar radiating element having a high band portion and a low band portion, the high band portion and the low band portion interconnected by a portion of the generally planar radiating element, at least a portion of a first radiating portion extending generally perpendicularly from the portion of the generally planar radiating element interconnecting the high band portion and the low band portion,
- the generally planar radiating element disposed on the endo-housing in spaced apart relation to the ground plane;
- a ground contact extending from the generally planar radiating element in electrical contact with the ground plane;
- a feed contact extending from the generally planar radiating element, the feed contact coupled to the transceiver.
